Personal history: Hoping that his sister would have a special talent, Aro changes Didyme to a vampire. However, her talent is not what he had hoped for. Marcus and Didyme fall in love and are “tremendously happy.” Marcus is so happy that he is no longer interested in “Aro’s plans for domination.” After a few centuries, Marcus and Didyme consider leaving the Volturi. Aro pretends to be happy and gives his blessing. However, he does not want to lose Marcus’ talent. When he knows that he cannot be discovered, Aro murders his sister even though he truly loves her. Marcus becomes an “empty man” with Didyme’s death. (SMW)
